摘要

全氟烷基和多氟烷基物质(PFASs)是一大类新兴的有机污染物,污染环境、食品和消费品。纺织品和其他户外产品是PFAS暴露的主要来源,因为它们的防水浸渍。纺织品中全氟磺酸的测定对于提高纺织品对循环经济的贡献越来越重要。虽然根据《关于持久性有机污染物的斯德哥尔摩公约》和REACH法规,某些关键化合物存在最大限量和限制,但目前还没有经过认证的参考物质(crm)。为了解决这一问题,开发了第一个用于测定户外纺织品中PFASs的CRM (BAM-B003)。完全符合ISO 17034和ISO 33405的要求。这项工作展示了CRM开发过程的整个过程,包括准备、同质性研究、稳定性研究和价值分配。认证是基于BAM使用液相色谱串联质谱(LC-MS/MS)和稳定同位素稀释分析(SIDA)进行的内部研究。18种PFASs的认证质量分数范围从0.46微克/千克到69微克/千克,其中PFOA(69微克/千克)、PFOS(41微克/千克)和PFHxA(35微克/千克)的流行率超过法定限制。BAM-B003用于分析质量控制,有助于提高纺织品的化学安全,加强循环经济。

Development of a certified reference material for per- and polyfluoroalkyl substances (PFAS) in textiles.

Per- and polyfluoroalkyl substances (PFASs) are a large group of emerging organic pollutants that contaminate the environment, food, and consumer products. Textiles and other outdoor products are a major source of PFAS exposure due to their water-repellent impregnations. Determination of PFASs in textiles is increasingly important for enhancing their contribution to the circular economy. While maximum levels and restrictions exist for certain key compounds under the Stockholm Convention on Persistent Organic Pollutants and the REACH regulation, certified reference materials (CRMs) are not currently available. To address this issue, the first CRM for determining PFASs in outdoor textiles (BAM-B003) was developed. It fully complies with the requirements of ISO 17034 and ISO 33405. This work presents the entire process of CRM development process, including preparation, a homogeneity study, a stability study, and value assignment. Certification was based on an in-house study at BAM using liquid chromatography tandem mass spectrometry (LC-MS/MS) with stable isotope dilution analysis (SIDA). The certified mass fractions of 18 PFASs range widely from 0.46 to 69 µg/kg, with a prevalence of PFOA (69 µg/kg), PFOS (41 µg/kg) and PFHxA (35 µg/kg) exceeding legal limits. BAM-B003 is intended for analytical quality control and contributes to improving the chemical safety of textiles and strengthening the circular economy.

期刊介绍: Analytical and Bioanalytical Chemistry’s mission is the rapid publication of excellent and high-impact research articles on fundamental and applied topics of analytical and bioanalytical measurement science. Its scope is broad, and ranges from novel measurement platforms and their characterization to multidisciplinary approaches that effectively address important scientific problems. The Editors encourage submissions presenting innovative analytical research in concept, instrumentation, methods, and/or applications, including: mass spectrometry, spectroscopy, and electroanalysis; advanced separations; analytical strategies in “-omics” and imaging, bioanalysis, and sampling; miniaturized devices, medical diagnostics, sensors; analytical characterization of nano- and biomaterials; chemometrics and advanced data analysis.
